Manipulate dynamically allocated array -Problem-

[borchu]

Hello everyone,

I am trying to manipulate "DYNAMIC ARRAY" Structures however I've been faced with problems wanting adding new value. Here my code:: -I use CodeBlocks and gnu gcc compiler ^ also I checked it on linux machine.

#include <iostream>
using namespace std;

#include "Deneme.h"

Deneme::Deneme()
{
    countReg = 0;
    pArray = new int[(countReg+1)];

    for (int i = 0; i < countReg+1; i++)
    {
        pArray[i] = NULL;
        cout<<pArray[i]<<"\t";
    }
    cout<<endl;
    cout<<"CONSTRUCTOR: "<<endl;

}


Deneme::~Deneme()
{
	cout<<"DESTRUCTOR: "<<endl;
	delete [] pArray;
}

void Deneme::insertEl(int id)
{
    cout<<"Element "<<id<<" has been added "<<endl;




    pArray[countReg] = id;

    /** display */
    for (int j = 0; j < countReg+1; ++j)
        cout<<pArray[j]<<"\t";
    cout<<endl;
    cout<<endl;
    /** end display */

    int* tempArray;

    tempArray = new int[(countReg+1)];

    for (int j = 0; j < countReg+1; ++j)
    {
        tempArray[j] = pArray[j];
        cout<<tempArray[j]<<"\t";
    }
    cout<<endl;

    delete [] pArray;
    pArray = tempArray;
    countReg++;


}

int main()
{
    Deneme D;

    D.insertEl(207);
    D.insertEl(98);
    D.insertEl(87);
    D.insertEl(112);
    D.insertEl(122);



    return 0;
}

I tried another version that pArray = NULL in Constructor ^ pArray = new int[countReg+1]; in insertEL function but at this time I can not keep before adding data, pls help I am working on this homework for many hours but I could not manage to throw integer || objects- later work- datas pArray pointer-dynamic array, thank u for ur help...

Let me say, using <vector> is forbidden.
